SAFETY-WRINGEB MECHANISM.

Application filed July 24,

' wringer, whereby release of the safety mechanism automatically releases the upper tensioned wringer roll but does not result in the disengagement or throwing out, from the wringer, of any part of said safety mechanism. a

My invention contemplates a safety release mechanism simple and efiicient and which will overcome the great disadvantage of the safety mechanisms usually employed in the type of so-called wooden frame wringer, that is, upon release of the safety mechanism, either the hurling entirely from the machine of parts of the safety mechanism or such disengagement that makes necessary a replacement of various parts, @perators of washing machines or wringers usually lack mechanical skill and no matter how simple the replacement of portions of a safety mechanism, after release may be, there is undoubtedly confusion: I

My present safety mechanism permits instant release of the upper wringer roll and a very small amount of adjustment to replace said wringer in its normal operating position.

Other objects of my invention will appear in the following specification in connection with the annexed drawlngs in which:

Figure 1, is a plan view ofthe wrin er.

Figure 2, is a side elevation thereo Figure 3, is a rear elevation. Figure 4, is an enlarged detail of the release handle and connected portions, and

Figure 5, is an enlarged detail of my particular release mechamsm.

Referring to the drawings, in Figure 2, is shown a conventional wringer, capable of being used with most types of washing machines. Inasmuch as my invention is directed mainly to the safety mechanism of the wringer, I have not deemed it necessary to include even power connections with the washer.

1922. Serial no. 578,973.

A power shaft 10 has connection with the power plant of a washing machine not shown; A power roll 11 has connection with the power shaft and is mounted in the conventional manner in the frame portions 12 of the wringer. The wringer itself being conventional, I am not including a de-' tailed description thereof and mere] indicate at 13, a housing member whic encloses the conventional gears, not shown. which permit motion being transmitted from the lower powenroll to the removable upper wringer roll 14. The upper or tension wringer roll 14, has at either ,end bearing blocks 15, which are slidable in guide ways in the frame portions 12. In these guide ways are mounted the tensioning springs 16, which engage, at their lower portion, lugs 17. on the bearings'15.

My safety mechanism is mounted entirely in the head portion 18, of the wringer and is made mp of the following portions:

Pivotally mounted at 19, in the head portion, are brackets 20, slidable in cut-out portions in the head. These brackets have at their outer ends the receiving portions 21, which have inserted, therein, the tensioning screws 22. Lugs 23, inserted in the up er portions of the tensioning springs '16, a at the lower end of the screw members. Brackets 20, as shown in the enlarged detail in Figure 5, are formed in such manner that a lower projecting portion 24, thereof, extends, in its normal position, as shown in full lines in said figure, slightly below the' head portion. A catch 25, is formed in this lower portion and is capable of receiving a release arm to be described later.

I have shown at 26, a release handle which may be of any desired form. From handle 26 depends the pin member '27, the same being pivotally seated in head member 18 and having positively attached thereto, as at 28, a short bar 29. This'short bar has pivotal connection at 30, with the releasing arms 31, which are capable, at their outer end, of engagement with the catches 25, on the brackets 20. At 32, are shown guide and support members for the releasing arms and it may be noticed that these members are wide enough to permit sliding of the A arms 31, even in the distorted position shown in dotted lines in Figure 4. *A small lug 33 is shown on the lower portion Qeehof the brackets 20, and this lug, as shown in the dotted line position in Figuret, abuts the lower side of the head portion when the safety mechanism has been released and thus prevents the released tensioning sprin s from throwing the brackets entirely from t e head portion and, as a matter of fact, permits sufficient release of the upper wringer roll 14, but does not allow the various portions of the safety mechanism to be disengaged to such an extent that agreat deal of adjustment is required in replacement. Sto 34, is disposed upon the lower face of hea member 18 and lies in the path of the short bar 29 and serves to prevent said bar from being thrown into a reverse acting position.

The operation of my safety mechanism for wringers is as follows:

In Figure 2, in heavy lines, is shown the normal positioning of my mechanism with the brackets 20, lying longitudinally of the head portion and with the releasing arms 31, engaging the catch portions in the brackets 20. The releasing arm extends longitudinally of the head portion at this time. Such positioning of the releasing levers and brackets 20, permits adjustment of the tensioning screws 22, upon the tensioning springs 16, to

hold the up er wringer roll 14, in its correct tensioned re ation with the lower ower roll 11. It may be seen that any tension that is desired is permitted by either screwin or unscrewing of the members 22. ,Should it be desired to release the safety mechanism, the handle member 26, is struck by the operators hand in such a manner that it will be drawn to an off-centered position, or lie in such manner that the short bar 29, will be turned at an angle to withdraw the releasing arms 31, from the catches 25, in the brackets 20, thus permitting the release of the tensioning springs 16, and thereby, the upper wringer roll 14. The lugs 33, do not permit the tensioning springs 16, from being thrown entirely from the frame members and even in their released condition, they necessarily abut the receiving ends 21, of the brackets.

In order to return the safety mechanism to its normal position, it is merely necessary to unscrew the members 22, in the receiving portions 21, until the brackets lie normally in their cut-out portions inthe head. 'The length of the tensioning springs and form of the brackets 20, permit the lower portions 24, of said brackets to assume their normal position, and thereupon the releasing handle 26, is returned to its normal position, that is, longitudinall of the head and the releasing arms are again thrown into engagement with the catch portions on the brackets. All that is necessary now is to re-tension the screw members 22,.and therefore the tensioning springs and upper wringer roll, with the result that the wringer is again in normal and operative position.
